GUIDE FOR .ROLLING-MILL S.

To all whom it may concern:

Be it known that I, THEODORE-H. NYE, a citizen 'of the United States,residing at Vorcester, in the county of \Vorcester and Commonwealth ofMassachusetts, have invented a new and useful.Improvement .in Guides forRolling-Mills, of which the following is a Specification, accompanied bydrawings forming a part of the same, in which v j Figure 1 represents afront elevation of a rolling mill housing provided with a guideembodying my invention. Fig. 2 is a sectional View of my improved guideon a larger scale, and shown on the plane of the broken line 2-2,Fig. 1. I

Similar reference letters. and figures refer to similar parts in theditferent views.

The object-of my present invention is to provide an improved mode ofattachment for rolling mill guides which will securev maximum rigidityand also facilitate their application to and removal from a rolling millhousing, and it consists in the construc-* tion and arrangement of partsas hereinafter described and pointed out in the annexed claims. 7

Referring to the accompanying drawings 1, 1, denote the housings and 2,2, a pair of rolls journaled therein. i

3 denotes the guide supported on a bar t attached to the front of thehousings by bolts 5. f, and verticallyadjustable by means of slots 6, 6.The guide 3 may be used either with or without guide plates, a 'pair ofwhich, in the present instance, are shown at 7 and8. The bar 4 extendsacross the housing and is provided on its upper side with thelongitudinal bearing surfaces 9 and 10 upon which the guide rests, andalong which ,itis horizontallyadjustable to bring it in alincment withthe circun'iferential grooves or passes 11' of the rolls. The guide 3 isprovided-at its outer iid with a downwardly projecting apron 12,provided at its lowe1 end with a slot 13 for the receptionof a bolt-'14,having a head lo'horizontally-ad- .ju stable along a T shaped slot 16,having a central opening 17 on its upper side to allow the bolt 14; tobe inserted in the slot. The upper surface of the guide bar tis alsoprovided with an undercutor doveta led shoulder'18 to receive acorresponding'doves tailed shoulder 19 formed on the under side of theguidei When the guide is placed in position, with s thedove-tailedshoulders 18 and 19 engaging each other, as shown in Fig. 2,and with the bolt. 14 inserted, the nut 20 is tightened sufficiently toprevent the disengagement of the dovetailed shoulders 18 and 19, therebyholding the guide rigidly in position for use. By loosening the nut 20slightly, the guide may be horizontally adjusted on the bar 4, or theslotted apron 12 may-be lifted off the bolt 14, and the guide removed.

In case the metal moving through the rolls becomes accidentallyimpeded,- forming what is known as a cobble, the strains upon the guidewill become sufficient to lift it from its attachment to the bar 4,thereby preventing the destruction of the guide, or the bolt .14 may bemade sutticiently weak to allow it to break under any unusual strainapplied to the guide, the ()bJQCt bemg to allow the guide to'b'e(lisp-laced whenever a cobble ls formed, thereby preserving the guideand facilitating the removal of the cobble. The

guide is held by a single nut 20 on the front of the apron 121andinconvenient position to be' reached by an attendant, rendering it anextremely easy matter to either attach or remove the guide or ad us t itas desired upon the bar 4. Any lifting strain exerted upon the guidewill be positively resisted by the dovetailed shoulders 18 and 19, whichare held in engagement bythe longitudinal strain resisted by the'bolt 14and also by the frictional contact between the nut 20 and the apron 12.If-the frictionali resistance between the nut 20 and the apron 12, orthe tensilestrength of the bolt 14 is less than the accidental liftingstrain imparted to, the guide, the latterwill be raised from its seat.

On the right hand side-of the rails in Fig. 2 I have shown a guide :21which used without any-guiding plates, but isjprovided with a method'ofattachment to theguide bar 22, as already shown and described'withreference to the, guide 3, being provided with an apron 93, .having aslot 21' to receive a bolt 25, having a head 26 and a nut QT, by

which the. dovetailed shoulder 28 of the guide 1s held in engagementwith a. corresponding dovetailed shoulder 29 on the 105 sageof metaltherethrough .will produce 119 torque. By holding the end'of-th'e guidenext the rolls by the interlocking dovetailed surfaces 18 andl9,"loc'ated in a vertical plane as far as practicable behind the vertical plane of the attachment by the apron 12 and bolt ll, enables theguide to be held in place by a comparatively light apron and a smallbolt.

I claim, l. A rolling mill housing having a guide supporting ,bar,. aguide mounted thereon,

said guide and said bar provided '-with reentrant engaging surfaces tohold said guide from vertical movement," and mean for holding saitlsurfaces in engagement y a strain toward the rolls of the rolling mill.

2. A rolling mill housing having a guide supporting bar, a guide mountedthereon,

said guide and said bar provided with re-' entrant engaging surfacestohold said guide from vertical movement, and a bolt para lel' with thelongitudinal an'is of said guide for lioldingsaid surfaces inengagement.

3. A rolling mill housing having aguide" supporting ,bar, a guidemounted thereon, said guide and said bar provided with 're-'; entrant'engaging surfaces for holding said gui'de from vertical movement,butarranged to allow horizontal movement away from the rolls of the rollingmill, said bar having a slot parallel with said surfaces, said guidehavin a detiendin flan e outside of said guide and said bar near the-endof,said guide next said rolls, with the surface on said guideoutside ofth surface on said bar, and means parallel with the longitudinal axisxofsaid guide at or near the opposite end of the guide for holdingsaidsurfaces in engagement by" a strain towatrd said rolls.

a A rolling mill housing having a guide supporting bar, a guide mountedthereon, said guide and saidbar'provided with "reentrant engaginjgsurfaces arranged to hold said guide from "vertical. movement, but toallow horizontal movement of said guide in a direction away from therolls of the rolling mill, and means for holding said surfaces inengagement.

. 6. A rolhng mill housing having a guide supporting bar, 'a' guidemounted thereon,

said supporting bar and said guide provided with reentran t engagingsurfaces, whereby the inner end of said guide is held from verticalmovement,.and means attached to said-bar, f r fiictionally holding theouter endof said guide from vertical movement.

7; Aro'lling-inill housing having a guide supporting bar, a guidemounted -'thereon, said supporting bar and said guide provided withreentrant engaging surfaces,whereby the inner end of said guide is heldfrom vertical movement, and a bolt held in said bar and'in frictionalcontact with said guide, ar-

ranged to draw said surfaces 'into' engage mentand to hold the outeren'd of said guide from vertical movement.
